LACE FABRIC.

Specification of Letters Patent.

Application filed February 17, 1811.

Patented. Apr. M912.

Serial No. 609216.

To all whom "ii may concern:

Be it known that l, l'IlIliHANX Biisciinn. a citizen of the German Empire. residing at Langerteld. near Barmen. in the Province of Westphalia and Kingdom of Prussia. Germany, have invented certain nevv and useful Improvements in Lace Fabrics; and I do hereby declare the following to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention consists in a novel lace fabric constituting a new article of manufacture as hereinafter more fully described and claimed. I

In the accon'ipanying drawings: Figure 1 represents diagrannnatically suitable meclr anism for producing the said article; 2 represents a plan view of a piece of lace produced thereby and embodying said invention.

T he texture l is formed in a well-known manner on a mandrel su 'iported on a pillar and passing through the thread-collector 2, the fabric in the example illustrated being united at its edges to form a tubular structure by means of three auxil- -iary threads 4, 5 and 651 These auxiliary threads are workedoin in the manner evident from Fig. :2, that is, the middle thread 5 twines alternately around the two others 4- and 6, the-latter tivo threads being drawn in the form of loops 4 or (3 through the marginal loops of the lace fabric proper, so that when the middle thread 5 is removed the two other auxiliary threads 4-, (3 can be detached whole from the lace t'abric. Above the thread-collector the mandrel which is round in cross-section up to that point hecomes of the shape ot'a flattened tube and passes in a manner well-known in itself in the shape of an 8 around the drawing-oil rollers 7. 8 provided above said thread-collector. Behind said rolls themandrel has again a round cross-section at its end part and at this part the rotary knives 9 revolving in tl'ie'direction of the arrow are provided, which knives engage in grooves in the mandrel and cut the loops of the middle auxiliary thread near the loops 4, (3 of the threads 4, G on the fabric nioving over the mandrel. The various pieces of the thread 5 form the waste, While the threads 4, 6 wh'telrbecome free by said thread 5 being cut are wound on bobbins 10 or 11 sothat they all be used again. The texture thus opened is then delivered out of the machine passing in a tlat condition over the roller 12.. In order to clear the threads at, 6, which are to be Wound up. from the pieces of the thread 5 possibly still adhering to them. said threads 4-, 6 are suitably passed through a thruid-cleaner before they reach the bobbins 10, ll.

.\s is evident the fabric in the (use of the process according to the present invention is passed through the drawing-oft mechanism while still in the form of a tubular structure, so that it is impossible for it to become distorted. in spite of this. however. the subsequent removal. of the auxi iary threads by hand, which occupies extremely much time and is also expensive is avoided and iliurthcr. some oi. the auxiliary threads are regained.

What I claim as my invention and desire to secure by Letters Patent is:-

l. A textile fabric consisting oi. longitudinal parallel threads and pairs of additional llll"tl(l5 passing in zigzag arrangement and opposite directions about: said longitudinal threads and each other auxiliary longitudinal threads 4 and (5, one of which. arranged within the border oi each set of threads aforesaid and in proximity to the inner longitudinal thread of that. series and another auxiliary thread 5 extending in zigzag course from side to side of the space between the tvvo longitudinal series first named and engaging alternately looped portions of auxiliary threads 4 and (3, which portions extend inward between the inner longitudinal thread on each side and that part of one ot' the said additional threads pussinn around the same substantially as shown.

A textile t'abric coi'isistinglj of longitudinal. threads. additional threads arranged in pairs passing in reverse zigzag arrangement about said longitudinal threads at the borders of the fabric, auxiliary threads Within the borders of the fabric and a. zigzag thread which crosses from one border to the other alternately engaging said auxiliary threads-and drawing theni through the proximate parts of the nearer members 01 the zigzag additional threads first above mentioned.

3. A textile fabric consisting; 0t longitudinal threads, additional threads passing in reverse zigzag arrangemeiu about said longitudinal.threads at the borders of the tabric, auxiliary threads engaging said additional threads and a zigzag thread which crosses from one border to the other engaging alternately said auxiliary threads and drawing them through the proximate parts of the zigzag additional threads first above mentioned.

4. A fabric provided with closing threads comprising four. closing interlocking elements, the latter consisting of longitudinal threads, additional threads passing in a. zigzag line about them, auxiliary threads in the two borders and a zigzag thread which passes from border to border alternately engaging said auxiliary threads and drawing them through the proximate parts of said zigzag auxiliary threads as set forth.

5. A textile fabric consisting of a plurality of sets of an odd number of longitudinal threads, an auxiliary thread passing in longitudinal zigzag fashion around sev eral of said longitudinal threads, including the central one thereof, another auxiliary thread passing in zigzag fashion around the remainder of said longitudinal threads and the central longitudinal thread of each set and interlocking through the loop of the other auxiliary thread at the point of intersection with the central longitudinal thread of each set, and threads connecting said sets of longitudinal threads.

In testimony whereof, I have signed my name to this specification in' the presence of two subscribing Witnesses.
